This was the script mentioned in my report:
;KOCH C
;Draws a sequence of Koch “C” curves. The size of the curve is determined by
n≤256; its position in the sequence by p≥0.
;The embedded, tabbed routine, kc, below is a “daemon”, which actually draws
the curve. The daemon draws the p=0 curve directly, and the (p+1)th curve by
replacing the line segments of the p=1 curve with scaled-down pth curves ( p≥0).
;The main kcurve-routine, “wrapped around” the daemon, merely positions the
drawing-point so that the curve appears in the centre of the page. It also
colours the sub-curves of the curve to show how the Koch “C” curve is
constructed.
;Run the script in LibreOffice by accessing the LOGO-toolbar and hitting the
green triangle button
;lines preceded by a “;” are ignored by logo

Try the script attached. Works in 16.04 and OS "Tumbleweed", but in
Bionic, LO freezes-up. I have to force a quit to get it back. Other
logo scripts behave the same. Shame. Being able to run LOGO in LO is
really cool.
I got an error message when I first tried to report this bug. Take 2
